Race calendar · April 2027
71 marathons across the US in April 2027, sorted by date. Which weekends are busiest, what the fields actually run, entry fees, and where each one starts.
April is prime marathon season across much of the United States. Winter training blocks wrap up right on schedule, daylight is long enough for early morning long runs, and temperatures in the mid-Atlantic, Midwest, and Pacific Coast have settled into the kind of conditions that make a 26.2 feel possible.
Spring weather is never a guarantee, though. Fronts move fast in April, and a warm week can flip to cold winds or rain by race morning. The Southeast can already feel genuinely hot late in the month, which changes pacing and hydration strategy in ways a runner who trained in cooler weather may not be ready for.
April marathons spread across the whole country and across every weekend of the month, so finding one that fits your schedule is straightforward. What takes more thought is matching the course to your goal, whether that is a fast, flat route or a marquee event with a charged atmosphere.
What the field actually runs
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.
When in April
Marathons are not spread evenly across April. Here is how the calendar actually falls, weekend by weekend, which is the part worth knowing before you book a trip or plan a taper around one.
By the numbers

Dress for the first mile, not the finish, and expect to shed a layer. A lightweight long-sleeve or arm warmers over a singlet covers the cool start in northern cities while giving you something to tie off later. In the South or Southwest, skip the extra layer entirely and plan your water intake from mile one.
It can be, if you pick the right course. April has point-to-point and net-downhill routes alongside hilly options, so the course profile matters more than the month itself. Weigh the elevation chart carefully before you register, and confirm the course is certified for qualifier purposes.
A standard marathon build runs roughly sixteen weeks, which puts the start of a serious training block in late December or early January. That means your long runs land through February and March, some of the coldest and most unpredictable weeks of the year in much of the country, so factor that into your plan.
April is a reasonable month to travel because the weather window is wide, flights and hotels are not as compressed as peak summer or fall weekends, and many races sit inside a larger festival weekend that includes shorter distances for family or friends who are not running the full 26.2.
The busiest weekend is April 24 and April 25, with 19 of them, 11 of those on Saturday, April 24. Another 3 fall on a weekday, which is worth knowing if you are traveling for one.
Across the 41 of these April marathons with published results from past editions, the median finisher ran 4:28:20, and the median winning time was 2:43:29. So anything under 4:28:20 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
The median one finished 104 runners, across the 41 of these April marathons with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 6:51:59.
California has 7, Ohio has 4, Virginia has 4, Wisconsin has 4, Florida has 3. If you are willing to travel, those are the states where an April weekend gives you the most to choose from.
